A4VTG071 hydraulic piston pump is variable axial piston pump with swash plate.A4VTG071 hydraulic piston pump is designed for hydrostatic drives in closed circuit.

A4VTG071 hydraulic piston pump flow is proportional to the drive speed and displacement.The flow of A4VTG071 hydraulic piston pump increases as the angle of the swash plate that is adjusted from zero to its maximum value.

A4VTG071 hydraulic piston pump flow direction changes smoothly when the swash plate is moved through the neutral position.

Two pressure relief valves of A4VTG071 hydraulic piston pump is provided on the high pressure ports to protect the hydrostatic transmission from overload.
